yes you have to take out the dash and the glove box to get it out. its on the passenger site in a black plastic housing.

yo man, idk if this is exactly what your problem is but my 1991 gmc sierra was doing the same fuckin thing and ****, and i took it to the gm dealer and had them look at it and my connectors and my ignition switchs were fried, also my truck was having a problem shitfing once those went but i also had that problem, perhaps yours is somehwta liek that as well... hope i could help

what size brake shoes go on a 2 wheel drive 95 GMC SIERRA

Code 44
oxygen sensor detecting lean exhaust

Note that many problems that show up as transmission issues are actually PCM or electrical, and may be external to the transmission. Try a different PCM, and check for chafing where the cables come out of the PCM.

The transmission is on the same fuse as the MAF, O2 sensors and at least one other sensor - if an O2 shorts out, it will blow the fuse and the trans will go into limp-home mode. Be sure the trans has power and the fuse is not blown before doing anything else.

Limp mode is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Check the wire harness clip on the transmission, passenger side by the catalytic converter. Look for any damages due to corrosion or brake in the wire leads. it's common for the clip to brake and the wire harness to loosen causing the transmission in to limp mode. Good luck and keep me posted, be glad to help you get your transmission running again soon and please rate.

Check for check ball wear on the separator plate and address it if needed. The 1-2 check ball wears out and sometimes the check ball blows through or sticks in the plate causing troubles.

Just thought I would point out a few items to think about. Good luck.

This is for one with intermittant wipers.

on opposite side of fuel pump relay .there the relay and fusible link then at the end there is a small block it contains the fuse 20 amp

ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
this is for the fuel system, relay for the injector is nearly the same.

In the beginning you should check for voltage and ground.
The 50amp fuse marked AC powers the blower motor and the motor is grounded.
The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.
You may need a shop manual or repair book to get the diagrams.

The cargo light will only work if the lights in the cab are on. Turn them on then flip the switch for the cargo light and it should come on, if not then it is probably an electrical problem.
